logger

A simple logger for C++ projects

Logger levels

The logging levels are in this order. When the reporting level for the logger is specified, all logging levels below it are reported.

• ERROR
• WARNING
• INFO
• DEBUG
• DEBUG1
• DEBUG2
• DEUBG3

Usage

#define REPORTING_LEVEL DEBUG // Maximum logging level is DEBUG
#include "logger.h"

int main() {
  const size_t cnt = 10;
  // LOGS all the messages since INFO is lower than debug
  LOG(INFO) << "Counter ahead";
  for (size_t i = 0; i < cnt; i++) {
    // LOGS only every other iteration when the condition is satisfied
    LOG_IF(DEBUG, i%2==0) << i;
  }
}

Output from example

INFO 09:56:45 [example.cc:6] Counter ahead
DEBUG 09:56:45 [example.cc:8] 0
DEBUG 09:56:45 [example.cc:8] 2
